Scientists watching the skies for asteroids that may threaten Earth have hit a new milestone, spotting the 10,000th sizable space rock that circles the sun near Earth's orbit.
The detection comes as part of NASA's ongoing planetary defense work, which discovers and monitors space rocks in the inner solar system to assure that no large asteroid is on course to impact Earth.
First quadruple asteroid discovered in the solar system
Astronomers have discovered the first known quadruple asteroid system. A team from Thailand and France spotted a third moon orbiting the main-belt asteroid Elektra, moving the object into the record books.
The asteroid Elektra, orbiting the Sun in the outer region of the main asteroid belt, was first discovered in 1873, with a sizeable diameter of around 200 km (124 miles).

Psyche, a metal asteroid about 226 km (140 miles) in diameter, is one of the most intriguing targets in the main asteroid belt.
Evidence of giant asteroid strike may be buried under Wyoming | Science | AAAS
Some 280 million years ago, before the rise of the Rocky Mountains—or even the dinosaurs—a 2.5-kilometer-wide asteroid smashed into the supercontinent of Pangaea, near the eastern border of present-day Wyoming.
Despite the tumult on Earth’s surface, however, plate tectonics had the last laugh. Intruding oceans and shifting landscapes buried the resulting 60-kilometer-wide crater—about the size of Rhode Island—in a tomb of sand that eventually became sandstone.
These massive asteroids hit Earth; check out the size and carnage caused
The planet Earth has been around for more than 4.5 billion years. And in the course of its history it has been hit by asteroids at least 190 times.
But before that, let's give you an idea of why these three asteroids or any asteroid that makes it to Earth are so special. In its 4.5 billion years history, Earth has been exposed to hundreds of thousands of asteroids, however, there are only 190 craters discovered so far. Why is that?
Asteroid Day Returns To Luxembourg With Astronauts Speaking About ASteroids And New Space Technology
Asteroid Foundation's annual Asteroid Day activities will return to Luxembourg June 29 through July 2nd. Confirmed invitees include NASA astronauts Steve Smith and Ed Lu, ESA astronaut Michel Tognini, Cosmonaut Dorin Prunariu and XPRIZE CEO Anousheh Ansari.
A foretaste of this technique was given by the dust fragments returned from the stony asteroid Itokawa by the Japanese mission Hayabusa in 2011. Most recently, the Hayabusa 2 mission landed samples from carbonaceous asteroid Ryugu in Australia in December 2020.
Newly Discovered Trojan Asteroid Has Same Orbit as Earth - The Debrief
In our solar system, there are locations known as Lagrange points. From a gravity standpoint, these locations are relatively stable, meaning that objects residing in them more or less hold their location.
From time to time, asteroids can become trapped in these Lagrange points. Due to its massive gravitational pull, Jupiter has over 10,000 such space bodies, known as Trojan asteroids, sitting in its various Lagrange points.
Huge asteroid the size of the Empire State Building to make close pass to Earth this week
A MASSIVE space rock will fly past Earth this week in a nerve-shredding close shave, according to Nasa.
Asteroid 2022 BH7 will make its close approach on Friday and is projected to be as long as the Empire State Building.
Nasa's Jet Propulsion Laboratory has provided a rundown of the space rock on its near-Earth Object (NEO) online database .
